[0047] There are two lifting rods for the bottom mold of the bottle blowing machine, each of which includes a connecting rod and a bearing arranged at the top of the connecting rod, for example, the bearing can be a spherical bearing, etc. When replacing bottles of different specifications, such as different bottle heights, the center distance of the two rods needs to be adjusted.
[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the present disclosure provides a device for adjusting the center distance of a bottom mold lifting tie rod of a bottle blowing machine mold, which is used as a tooling for adjusting the center distance of two bearings and includes:
[0049] Base 1;
[0050] A fixed shaft 3, wherein the bottom end of the fixed shaft 3 is connected to the first end of the base 1 along the first direction x, and the top end of the fixed shaft 3 extends upward and is used to be connected to the bottom end of one of the connecting rods;
[0051] A bracket 2 is disposed above the base 1, wherein a first end of the bracket 2 is rotatably connected to a second end of the base 1 along a first direction x in a horizontal plane;
[0052] A movable shaft 4, the bottom end of which is connected to the second end of the bracket 2, and the top end of which extends upward and is used to be connected to the bottom end of another connecting rod; and
[0053] The locking assembly is configured to lock the position of the bracket 2 relative to the base 1 when the distance between the center of the fixed axis 3 and the center of the movable axis 4 is a preset distance L, and the preset distance L is the center distance between the two bearings.
[0054] The fixed shaft 3 is fixed relative to the base 1, the movable shaft 4 is fixed relative to the bracket 2, and the bracket 2 is rotatable relative to the base 1 to adjust the distance between the fixed shaft 3 and the movable shaft 4. The fixed shaft 3 and the movable shaft 4 are both extended along the third direction z (i.e., the vertical direction). For example, the outer diameter of the fixed shaft 3 and the movable shaft 4 can be 15 mm, and the size can be set according to the aperture of the bearing.
[0055] The first end of the bracket 2 is connected to the second end of the base 1 through a first hinge shaft 5, and the first hinge shaft 5 is vertically arranged. The locking assembly has a locked state and an unlocked state. In the locked state, the bracket 2 is fixed relative to the base 1, and the position of the movable shaft 4 remains fixed; in the unlocked state, the bracket 2 is rotatable relative to the base 1, and the center distance between the movable shaft 4 and the fixed shaft 3 is adjustable.
[0056] When the adjustment device is in use, if it is necessary to adjust the center distance of the bearings of the two pull rods to a preset spacing L, for example, the preset spacing L is between 272.05-272.25. Step 1: Use a vernier caliper to adjust the center distance between the movable shaft 4 and the fixed shaft 3 to the preset spacing L. At this time, the angle between the bracket 2 and the first direction x is about 15°. After the position adjustment is completed, the bracket 2 is locked by the locking assembly. Step 2: Install the connecting rod and bearings of the two pull rods on the fixed shaft 3 and the movable shaft 4 respectively, and then lock the connecting rod. If readjustment is required later, loosen the locking assembly to free the movable shaft 4 so that the pull rod can be easily removed. If the movable shaft 4 is not unlocked, it is more difficult to remove the pull rod.
[0057] This embodiment can flexibly adjust the distance between the fixed shaft 3 and the movable shaft 4 by providing a movable bracket 2, so as to conveniently and quickly adjust the center distance between the bearings of the two tie rods, and reduce the difficulty of adjusting the center distance of the bottom mold lifting tie rod of the bottle blowing machine mold. Moreover, this device can realize continuous adjustment of the center distance, improve the adjustment accuracy, improve the safety of the equipment operation, and prevent the bottom mold from a large impact.
[0058] In some embodiments, Figure 1 As shown, the second end of the bracket 2 is located at a side away from the fixed axis 3 relative to the first end, and the second end of the bracket 2 exceeds the base 1 .
[0059] This structure can not only reduce the size of the base 1 along the first direction x, but also reduce the contact area between the bracket 2 and the base 1, so that the bracket 2 can be flexibly rotated in the horizontal plane for position adjustment. In addition, it is also convenient to install the movable shaft 4 on the part of the bracket 2 that exceeds the base 1.
[0060] In some embodiments, Figure 2 As shown, the base 1 includes:
[0061] A first flat plate 13, one end of which along the first direction x is provided with a fixed shaft 3;
[0062] The second plate 14 is connected to one end of the first plate 13 away from the fixed axis 3 along the first direction x, and both ends of the second plate 14 along the second direction y extend beyond the first plate 13, the second plate 14 and the first plate 13 form a T-shaped structure, and the second direction y is perpendicular to the first direction x; and
[0063] The first vertical plate 15 and the second vertical plate 16 are respectively connected to two ends of the second flat plate 14 along the second direction y and extend upward;
[0064] The locking assembly includes a first locking component 6 and a second locking component 7, which are respectively disposed on the first vertical plate 15 and the second vertical plate 16, and are used to lock the bracket 2 from both sides of the bracket 2 along the second direction y.
[0065] The base 1 of this embodiment is convenient for installing the bracket 2 and the locking assembly, and the first locking member 6 and the second locking member 7 respectively apply relative forces from both sides of the bracket 2 along the second direction y, so that the bracket 2 is subjected to balanced forces in the locked state. For example, the first locking member 6 and the second locking member 7 are arranged opposite to each other along the second direction y.
[0066] In some embodiments, Figure 2 As shown, the first locking component 6 includes:
[0067] A first locking screw 61 passes through the outer side of the first vertical plate 15 and is used to abut against a side surface of the bracket 2 along the second direction y to achieve position locking; and
[0068] The first locking nut 62 cooperates with the first locking screw 61 and is configured to achieve position limiting when being screwed to abut against the inner side surface of the first vertical plate 15 .
[0069] This embodiment can achieve position adjustment through the cooperation between the first locking screw 61 and the threaded hole on the first vertical plate 15, and the first locking screw 61 can be locked in position by screwing the first locking nut 62, so that locking and loosening can be easily achieved.
[0070] In some embodiments, Figure 2 As shown, the second locking component 7 includes:
[0071] A second locking screw 71 passes through the outer side of the second vertical plate 16;
[0072] A hinge block 73 connected to the inner end of the second locking screw 71; and
[0073] The limiting block 74 has a first end rotatably connected to the hinge block 73 in a horizontal plane, and a second end thereof is used to abut against another side surface of the bracket 2 along the second direction y to achieve position locking.
[0074] The second vertical plate 16 may be provided with a light hole for the second locking screw 71 to pass through, the hinge block 73 is connected to the inner end of the second locking screw 71, the limit block 74 is connected to the second end of the hinge block 73 through the second hinge shaft 75, and the second hinge shaft 75 is vertically arranged. During the adjustment process, the limit block 74 and the hinge block 73 will rotate at a small angle to ensure that the limit block 74 remains in contact with the side of the bracket 2.
[0075] The second locking component 7 in this embodiment can increase the matching area with the bracket 2 by providing the limiting block 74, thereby improving the stability of limiting the bracket 2 and further improving the accuracy of adjusting the distance between the fixed shaft 3 and the movable shaft 4.
[0076] Furthermore, the first locking member 6 is positioned against the side of the bracket 2 by the first locking screw 61, which makes the position adjustment faster and more convenient; the second locking member 7 is positioned against the side of the bracket 2 by the limiting block 74, which improves the limiting stability. Figure 2 The cooperation between the first locking component 6 and the second locking component 7 can improve the locking efficiency and the limiting stability at the same time.
[0077] In some embodiments, Figure 2 As shown, the limit block 74 is a trapezoidal block, and the inclined surface of the trapezoidal block cooperates with the bracket 2. When the bracket 2 is at an angle relative to the first direction x, this limit block 74 can better cooperate with the side of the bracket 2 and reduce the rotation angle of the limit block 74.
[0078] In some embodiments, the second locking component 7 further includes:
[0079] The two second locking nuts 72 are respectively located on both sides of the second vertical plate 16 and cooperate with the second locking screw 71 . The two second locking nuts 72 are configured to achieve limiting when being screwed to abut against the inner and outer side surfaces of the second vertical plate 16 .
[0080] In this embodiment, the position of the second locking screw 71 can be locked by two second locking nuts 72 . This fixing method can set a through hole on the second vertical plate 16 to prevent the limit block 74 from rotating in the vertical plane when adjusting the position of the second locking screw 71 .
[0081] In some embodiments, the first locking screw 61 and the first locking nut 62 may adopt standard thread to improve the locking efficiency of the first locking component 6 .
[0082] In some embodiments, the second locking screw 71 and the second locking nut 72 both use fine pitch threads to improve the position accuracy when locking the bracket 2, thereby improving the accuracy of adjusting the distance between the fixed shaft 3 and the movable shaft 4.
[0083] In some embodiments, Figure 1 As shown, the base 1 is provided with a first hole 11, the fixed shaft 3 includes a first connecting section 31, a first transition section 32 and a first mounting section 33 which are connected in sequence, the first connecting section 31 cooperates with the first hole 11, the first transition section 32 abuts against the upper surface of the base 1, and the first mounting section 33 is used to mount one of the connecting rods; and / or
[0084] A second hole 12 is provided on the bracket 2, and the movable shaft 4 includes a second connecting section 41, a second transition section 42 and a second mounting section 43 connected in sequence. The second connecting section 41 cooperates with the second hole 12, the second transition section 42 abuts against the upper surface of the bracket 2, and the second mounting section 43 is used to install another connecting rod.
[0085] This embodiment can conveniently fix the fixed shaft 3 on the base 1, and the first transition section 32 abuts against the upper surface of the base 1, which can prevent the fixed shaft 3 from shaking, improve the stability after installation, and help ensure the position of the pull rod; and can conveniently fix the movable shaft 4 on the bracket 2, and the second transition section 42 abuts against the upper surface of the bracket 2, which can prevent the movable shaft 4 from shaking, improve the stability after installation, and help ensure the position of the pull rod.
[0086] In some embodiments, Figure 1 As shown, the height of the first transition section 32 is greater than that of the second transition section 42 , and the tops of the first installation section 33 and the second installation section 43 are flush.
[0087] Since the bracket 2 is higher than the base 1, by setting transition sections of different heights for the fixed shaft 3 and the movable shaft 4, the tops of the fixed shaft 3 and the movable shaft 4 can be flush, so that the bearings of the two pull rods are at the same height.
[0088] Below Figure 1 and Figure 2 The specific embodiment is taken as an example to illustrate the use method of the center distance adjustment device of the bottom mold lifting tie rod of the bottle blowing machine mold disclosed in the present invention.
[0089] When the adjusting device is used, if the center distance of the bearings of the two pull rods needs to be adjusted to a preset distance L, for example, the preset distance L is between 272.05-272.25, the following steps can be used:
[0090] Step 1: Use a vernier caliper to adjust the center distance between the movable shaft 4 and the fixed shaft 3 to a preset distance L. At this time, the angle between the bracket 2 and the first direction x is about 15°.
[0091] Step 2: After the position adjustment is completed, screw the first locking screw 61 so that its inner end abuts against one side of the bracket 2 , and adjust the second locking screw 71 so that the limit block 74 abuts against the other side of the bracket 2 .
[0092] Step 3: Screw the first locking nut 62 to make it abut against the inner side surface of the first vertical plate 15 , and screw the two second locking nuts 72 to make them abut against the inner and outer side surfaces of the second vertical plate 16 , respectively.
[0093] Step 4: Install the connecting rods and bearings of the two pull rods on the fixed shaft 3 and the movable shaft 4 respectively, and then lock the connecting rods.
[0094] If readjustment is needed later, the first locking nut 62 and the two second locking nuts 72 are loosened to free the movable shaft 4 so that the pull rod can be easily removed. If the movable shaft 4 is not unlocked, it is difficult to remove the pull rod.
[0095] The above are merely exemplary embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
